I look at this way: There is a lack of TDs because people either do not want to work on FAF events or they are not willing to work with FTX
This is similar to there being VERY little people on the moderation team while Gorton was around because he himself was an awful moderator. Now that Gieb is in place - a much better manager - there are plenty of mods joining.
The real answer? I do not know, but i for one did not really enjoy hosting LoTS Group last year because the system was overly-complex and frustratingly long. The events tend to still go on way way too long and it makes the job of sitting around waiting forever unappealing to others who basically get a "thanks for hosting" and that is all.
I left the "ladder team" recently for similar reasons in that the debates on what map is good or bad was endless, often with FTX or arch shooting down any suggestions because they want "evidence." Arch nor FTX has any mapping knowledge and has to outsource it to biass or Jip to evaluate, so it gets rather cumbersome to take orders from people who hardly do it themselves.
I think it is great that FTX takes polls on opinions of this material, but in the end there are not really enough people with experience to make that valid. In the REAL world data sources are scrutinized for this kind of conclusions, and it makes me less than willing to actually work for someone who practices it.
